Frontend squeaks Montero sport 01

Hi, Bought a used 01 Montero sport. But the front end squeaks. Doesn't do it on the highway. It has 55k on it. It only does it when the suspension travels a little more then normal or on dirt roads. I lubed the sway bar links with silicon spray, and it helped. But still looking for where the other noise is coming from. Its just annoying, and would like to make it quit. Anybody else have this problem? Thanks Malcom
